HMC is a wholly owned subsidiary of Harvard University. The company’s president and chief executive is Jane L. Mendillo.

In June, at the end of its most recent fiscal year, the endowment had assets of $30.7 billion, essentially flat with its value at the end of its previous fiscal year. A Globe story on the endowment’s performance noted that steep declines in European and emerging markets wiped out gains in other areas.

Mendillo took over as HMC’s chief executive in mid 2008, just before the start of the financial crisis. The endowment posted a 27 percent drop in value for the fiscal year that ended June 30, 2009. Since then, Mendillo has focused on risk management and repositioning the portfolio so that it is more conservative and able to cash out of investments when necessary.
